    Description / Table of Contents: Zusammenfassung Bei 37 Kindern in Alter von 3–10 Jahren wurden telemetrische Messungen der Herzfrequenz während des regulären Schwimmunterrichts durchgeführt. Der im Stehen gewonnene Ausgangswert lag bei 122/min. Beim Schwimmen erreichte die Herzfrequenz im Mittel 150/min, stieg aber bis auf maximal 170/min an. Die höchsten Einzelwerte betrugen 210/min bei einem 6jährigen Mädchen und 204/min bei einem 6jährigen und einem 7jährigen Jungen. Beim Tauchen sank die Herzfrequenz innerhalb von 10 sec um 21/min und innerhalb von 20 sec um 38/min ab. Nach dem Tauchen stieg die Herzfrequenz rasch wieder an, blieb jedoch noch einige Zeit unter den vor dem Tauchen gemessenen Werten. Während des Tauchens wurden in unserem Untersuchungsgut die tiefsten Einzelwerte registriert, und zwar bei zwei 5jährigen Jungen jeweils 72/min. Die mittlere Herzfrequenz beim Hineinrutschen bzw. Hineinspringen übertraf mit 159/min die mittleren Werte beim Schwimmen. Die jüngeren Kinder erreichten sogar während des Rutschens und Springens häufiger den höchsten Wert als beim Schwimmen. Im allgemeinen erzielten Schulkinder während der meisten Phasen der Schwimmstunde höhere Herzfrequenzen als Kleinkinder. Der Höchstwert beim Schwimmen betrug z. B. für Kleinkinder 159/min, für Schulkinder hingegen 182/min. Dies lag daran, daß die größeren Kinder auf spielerische Anreize viel intensiver reagierten als die kleineren.
    Notes: Abstract Heart rate was measured telemetrically in 37 children of 3 to 10 years of age during regular swimming lessons. Starting from a resting value of 122 beast/min when the children were standing, the value increased to a mean of 150/min. A mean maximal value of 170/min was attained. The highest single values were 210/min in a 6-year-old girl and 204/min in two boys, 6-and 7-years-old. During diving heart frequency decreased within 10 sec by 21/min and within 20 sec by 38/min. After diving heart frequency increased again quickly, but still remained for some time below the value recorded before diving. During diving we found the lowest single values, 72/min in two 5-year-old boys. The mean heart frequency during sliding and jumping into the water was 159/min, which exceeded the mean heart rate during swimming. The smaller children up to 5 years attained maximal values even more often during sliding and jumping than during swimming. Generally, the heart rate during most periods of the lesson was higher in schoolaged children than in infants. For example the mean maximal value during swimming was 159/min in infants but 182/min in school-aged children. The reason was that the older children reacted much more intensively to friendly stimuli than the younger.

    Notes: Summary The case of a young female patient with neuroleptic malignant syndrome (NMS) and extended MRI white matter hyperintensity in the left parietal and both occipital lobes is reported. MRI lesions resembled findings in hypertensive encephalopathy, they were not readily compatible with CNS vasculitis. Venous sinus thrombosis could be ruled out. Vascular encephalopathy with transient white matter edema and a small residual left parietal lesion is suggested. Neurochemical implications are discussed with particular reference to a possible involvement of excitatory amino acids in NMS pathogenesis.
